Lesson 10 Weather

1. Fill in the blank spaces with the correct words.

Answer 👉 

a. The weather forecast made on the basis of observations taken by satellite is more trustworthy.

b. Change in temperature brings change in atmospheric pressure of the Earth.

c. Weather is variable from place to place.

d. When there is scorching Sun from the morning in the monsoon season, it is likely to rain in the afternoon.

e. The light of the Sun does not always fall directly on the Earth.

2. Write answers to the following questions.

a. What is called the weather?

Answer 👉 Weather refers to the day-to-day changes in atmospheric conditions, such as temperature, humidity, precipitation, wind, and cloudiness, in a particular place.

b. List the factors that bring change in weather.

Answer 👉 The factors that bring change in weather include temperature, pressure, wind, humidity, and precipitation, which are influenced by various natural phenomena like the movement of air masses, the rotation of the Earth, the Sun's radiation, and the presence of water bodies.

c. Why is it hot when the light of the Sun falls directly on the Earth?

Answer 👉 When the light of the Sun falls directly on the Earth, it heats up the surface, which then warms up the air above it. This causes the air to rise, and as it rises, it cools and forms clouds, which may lead to precipitation. This process is called convection, and it is responsible for making the atmosphere warmer when the Sun's rays fall directly on the Earth.

d. What is weather forecasting?

Answer 👉 Weather forecasting is the process of predicting the atmospheric conditions in a particular region for a specific time period. It involves analyzing data from various sources, such as satellite images, weather stations, and computer models, to make predictions about the future weather conditions.


e. What is the difference in humid air and dry air?

Answer 👉 Humid air contains more water vapor than dry air. This means that humid air has a higher relative humidity, which can make it feel warmer than dry air at the same temperature. Humid air also tends to have more cloud cover and a greater likelihood of precipitation than dry air.
